Historically, slaughterhouses and packinghouses have performed water treatment with a combination of fine screening, sedimentation, coagulation and flocculation, trickling filters, and an activated sludge process. Unfortunately, the chemicals involved have usually been commodity driven—that is, dictated more by price than safety or effectiveness. Acidic and caustic substances such as polyaluminum chloride and ferric chloride have been the viable coagulants chosen for their low cost and the large process water flows. A changing regulatory environment, however, and aging POTW infrastructure have required managers to rethink how best to treat the wastewater leaving their facilities.
What are the wastewater challenges facing slaughterhouses and packinghouses?
An overabundance of nutrients passing through to POTW’s or directly discharged into a nearby water source can have a drastically negative effect on the POTW’s ability to treat the wastewater and protect the environment. Such nutrients spur the growth of algae and phytoplankton in the water in which they eventually reside. This, in turn, depletes the water’s oxygen. Depleted oxygen levels in water will diminish aquatic life and negatively impact local wastewater treatment initiatives. As communities search for solutions, they discover that they lack the capital or tax base necessary to improve infrastructure to handle the increased nutrients. Increasingly, the problem has been redirected back to the slaughter and packinghouses to solve on their own.
